Is it definite that {download,updateext}.service.openoffice.org is going to be
switched off - and when is it?

/ExtensionUpdateService/check.Update is one of the most popular files - with
around 5-10 requests per second.

Please note however that my fallback of download.services.openoffice.org does
not have all features. It has the mirror redirection (the essential), but does
not serve cryptographic hashes for verification, no automatically generated
torrents, no metalinks.
If you compare the following two URLs, you can note the differences:
http://download.services.openoffice.org/files/stable/3.3.0/OOo_3.3.0_Solaris_Sparc_install-wJRE_en-US.tar.gz.mirrorlist
http://openoffice.mirrorbrain.org/stable/3.3.0/OOo_3.3.0_Solaris_Sparc_install-wJRE_en-US.tar.gz.mirrorlist
Also, what's not visible, is that the fallback host doesn't count downloads.
Mirror selection and redirection are the same. But as you might know, large
downloads benefit from means for download verification, which is why crypto
hashes and metalinks/torrents are useful, especially affecting downloaders with
not less-than-ideal connectivity.
To set up a full fallback, I am lacking the disk space, unfortunately. I don't
have space for the file tree. (I would appreciate donations for running costs
of disk space, or access to server, very much.)
But, no problem, there is the option of continuing by switching to my host as
it is.
Given there is hardware, I could set up a successor for
download.services.openoffice.org, respectively move it to a new home, if there
is interest...
Well I hope there is! I know I am biased, because I'm the one who built
download.services.openoffice.org, and spent some years with it. But I'd bet
some money that nobody wants to go back to pre-MirrorBrain times, where the
really close mirrors were always ignored when you downloaded OpenOffice.org...

By the way, here's a disclaimer: I'm also the "head" behind LibreOffice's
download system. Yes, if you might wonder: I am maintaining the download
servers of both projects and have no problem with that :-)
